The one thing that really made the OG LZ-GH was that the smooth curves of the chassis, the bar being one of those features. And I think for me it stood out as not being a pointy piece of metal with some buttons on it. I personally would love to see a more "round approach"

I don't mind the look of the square bar all, but the main reason I'm interested in the GH v2 is that owners of the GH v1 seem to praise its typing feel. Changing the bar from round to square will surely affect this--maybe for the better, but I would guess for the worse.
